Describes a landform that is gently undulating with a wave‐like relief. No particular process of origin is implied. Soils on rolling topography tend to show much local variation in texture. The pattern of variation follows the rhythm of the undulations, since fine particles tend to wash down from highs into hollows. Consequently the lower soils are enriched in the clay-fraction at the expense of adjacent soils upslope. Compare with soils in hummocky terrain in the article Ice Erosion.
